LUBRICANT CUP.

Application led November 24, 1922. Serial No. 602,940.

Our invention relates to lubricant cups and has particular reference to a cup of this character adapted for use in providing proper lubricationfor automobiles although the device may be used for various industrial purposes as well.

The primary object of our invention is a provision of a lubricant cup having a reservoir containing a supply of oil with a constant pressure thereon, whereby the lubricant is forced into the bearing and also` a proper retarding and feeding means for preventing the oil flowing from the cup too rapidly and supplying the proper amount to the bearing surfaces, the retarding and feed-l ing means being placed in a chamber in the lower portion of the cup and separated from the chamber forming the main reservoir.

Another and further object of ourinvene tion is the provision of a lubricant cup which is separated into compartments by a baflie having openings therein, one of which compartments serves as a main oil reservoir, and the other contains a packing material, preferably an absorbent in the form of wicking, which prevents the oil flowing from the cup too rapidly and which serves to convey the proper amount of lubricant to the bearing surfaces. i

Another and further object of our invention is the provision of a cup for supplying oil to bearings in the proper quantity and in the requisite amount desired to insure proper lubrication of the bearings with oil as distinguished from grease as has been the lubricating medium in common usage heretofore.

Another and further object of our invention is a provision of an oil cup having means therein whereby the bearing can be flushed with oil by means'of a suitable apparatus for applying pressure tothe oil so that the old and used oil is cleaned out of the bearing and the surface of thebearing coated with `new and fresh oil with a supply left in the lubricating cup so that the bearing is kept supplied with oil after the filling operation.

These and further objects of our invention will be more fully and better understood by reference to the accompanying drawings, 'and wherein- J Figure 1 is a side elevational view of our improved oil cup;

Figure 2 iS a vertical sectional view showing in detail the various parts of our improved invention;

Figure 3 is a cross-sectional view on lines 3 3 of Figure 2; and

Figure4 is a cross-sectional view on lines 4--4 of Figure 2.

Referring now specifically to the drawings, in which like reference characters refer to like parts throughout, a main body is provided having a base 11 which forms the bottom of the cup and a hollow stem 12 integral with said base projecting downwardly therefrom and which is threaded at its lower end and adapted to be secured to abearing, the `stem 12 forming the discharge conduit from the cup. The body 10 is made of brass or other suitable material and is turned down around the base 11 at 13 so that a secure joint is formed at this point, the parts hereinafter described being inserted in the body 10 before this operation i is y completed. Mounted within the body 10 and projected outwardly therefrom through an opening in the top thereof is a hollow stem 14 forming a charging port for the oil cup and to which a diaphragm 15 is attached at its lower end, with washers 16 and 17 on each side thereof, thewasher 16 being engaged by a shoulder 18 on the stem 14 and the washer 17 having the lower `end 19 of the stem turned outwardly so that the diaphragm 15 is -held in proper position in the member 10 and is bodily lmovable therewith. The diaphragm 15 has adownwardly extending marginal iange 20 at its outer periphery, the sides of the flange 20 being in frictional engagement with the inside port-ion of the body i 10. The member 14 is hollow and is internally threaded at its inner lower portion and has a plug 21 inserted thereiinand inV threaded engagementtherewith, the said plug 21 having a conduit 22'at the upper end thereof and a recess 23 at the lower portion within which a coil -spring24` is positioned, the lower end of the plugabeing turned inward to forma flange 25 which acts as a seat for the spring 24. A ball '26 is provided which is seated onthe upper-,end ofthe spring 24 and serves to close the conduit 22 in the upper end of the plug21 against the outward liow of oil. A second coil spring 27 is provided which isseated f upon the upper end of the plug21and has a ball 28 seated on its upper end, the said ball being in engagement with a seat 29 formed on the inner side of the end of the stem 14- so vthat two valves are provided which effectively prevent any escape of the oil from the cup after it has been il-led.

A coil spring Soie provided inthe body of the cup the upper end of which is seated against the upper portion of the'body tapered at 32 allowing for the easy attachw ment of?4 an oil gun to tlie stem 14 and has an* annular recess 33; therein within which p the jawsA of the connecting' means oli the' oill gun enga-ge so that an` oil-tight joint isA formed between1 oil gun and the cupi Positioned in the" lower part of the oil" cup' and? eXtendin transversely of said cup ist a balil'e' 321? having' ilsnia'rginalf edge 35 turned downwardly a-n'dl which` rests upon the' base ll of the oil,i cup a-ndl has a plurality oil' re-A cesses 36 therein, through which the oily liliass'esV to the chamber 35a iir the lowerV part of the cupi and within' which packingy is" placed?, preferably" an absorbent in the forni oit' a? wiclr', whichi entends into the discharge conduit lf2 and whichi prevents tl'ieoilI from escaping fromL the cup too: rapidly' and' I which allows-f the" proper amount ofoilto'be fief conveyed down toi the' bearing so that it is kept; properly lubricated', the balile 34* be'- spaced 'lirom t'hefbottoni of the body or the o'il cup. e'i'itrally` located oii the baffle 34 and secured thereto in alignment with the-center ol* the stem l@ isa pliigBSl'iavingl ai cenduit 39 extending longitudinally there o'li'lioan eifilargedA recess el() in the lower end oit the n'ebe'r 3l), an'dhaa'fing its lower edges 41:1' ti'irned inwardly' to form a seat for a` spring-1 lef, winch sseatedi within@ the recess 40;' lesaid plugl 38 llavinfg a-nl outlet 413 at the lower' endT thereof; The pllug'" 38; terminates: a s'hort' distance above the endl of the outlet plug 1Q andi extends vertically' of the plug' 1.2 andi has they packing heretoforeI desciiibedposi'tione'cl around! its outer sides. balil 44 is' seated; against shoulders 455 and serves@ ae al valvePto closethe conduit 39', the

, fence of the spring bein-'gigreater than the francel o'ii the spring' 30 as will-lf be more' fully describedI hereinafter. 11n the operationl of the" device, an oil gunf is connected.` tof the upper' end off! the member le' and pressure applied to the con-tents otthe* oillf gun; which has the* effect) of' forcing the` ball,- 2185 away troni-l itsseatv and afl-lbwingf the oil toI pass downwardly througlithe sten-1f 14% and unsea the balli- 265 front its seat so.: that; the oil?- pa'ssesr into! the' space 'between the baille Se' and thef diaphrwginwlf, compressirlgI the spring 8O and lling the chamber above the ba-filej 34e, the diaphragni 115 being; iorced upward' in the cupi so the stein 1'4"-v projects a short distance therefrom when the body 10 isnilled with oil. Pressure applied. ton the oilI in the gun forces the oil downwardly througlrthe openings 36 in the baliie 34, and as soon as the cup is filled, unseats the ball 4d: from"` ilts' seat and' forces oil downwardly through the member 38, into the bearing, tli-us iiushing' out'- the bearing' of allli u's'ed oil and providing new" andf clear-r oili fori the; bearing -by means of wl'iiichJ itl isproperly luL bricated. It will thus be understood that the cup is not only' filled withi oil, but that the cup provides means for properly flushL ing out a bearing whichA has'4 not beenv accomplished heretofore; In additi'oni thereto the packing is prevented from? becoming solid because th'e baille prevents` the full pres"-4 sure of the spring 30 from being exerted thereon and alsoI pre-ventsthe fullr for-ceo@ the oil from the' oilf guar being enertedl on the said packing, thus allowing the pack-A ii'ig' tol bef loosely positioned underneath the"4 baffle so the oil" cank easilly'fl flow there"- throught While we' have describedl more'v or lessv precisely the details of construction o-i" our invention, wey do not' wislr to` bel understood as limiting ourselves thereto, as we conteurpl'ate changes f inf forni!y andE thek proportionE of parts andi the substitution oitV eqniv'alentsi as circumstances? may suggest or; render ex? pedient, without' departing; from the spirit or scope of our invent-ilona Vile claim*- :1
